To (LZZ 1071/0/11 it m/uq concern:

Be it known that I, ARMIN R. FRIEDEMAN, a citizen of the United States, residing at Greatbend, in the county of Barton and State of Kansas, have invented new and useful Improvements in Cultivators, of which the following is a specification.

This invention relates to cultivators; and the primary object of the same is to provide a device of this character having means for leveling or breaking down listed ridges where wheat-stubble and weeds have been listed under and operating to throw up all trash on the surface to protect the grain or seed during winter.

A further object of the invention is to provide a simple organization of elements in a cultivator having readily-adjustable features to adapt the machine for different kinds of work.

A still further object of the invention is to dispose the weight of the operator or driver or locate the seat of the latter in such position with respect to the cultivating devices as to render the machine more effective in arriving at the result sought.

With these and other objects and advantages in view the invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter set forth.

In the drawings, Figure 1 is a top plan view of a cultivator embodying the features of the invention. Fig. 2 is a side elevation of the same. Fig. 3 is a transverse vertical section on the line 3 3, Fig. 2. Fig.4 is a detail perspective view of one of the disk-box arms and disks. Fig. 5 is an enlarged section on the line 5 5, Fig. 1.

Similar numerals of reference are employed to indicate corresponding parts in the several views.

The numeral 1 designates runners, which are held in parallel relation and connected by an intermediate brace-arch 2 and a rear seatareh 3, on which is secured a seat 4, the arch 3 being projected above the upper edges of the runners a considerable distance, as clearly shown by Figs. 2 and 3, and the seat 4 is held by this arch centrally with respect to the runners. The rear ends of the runners 2 are projected at an angle and have outer bevels 5 to provide clearances at opposite sides for the disk devices when the latter are adjusted inwardly close to the runners. This rearward extension of the runners is an advantageous feature in that they give a more stable support to the mechanism and permit the disposition of the seat of the operator at a point where the weight of the latter will be most effective 011 the cultivator-blades without liability of uneven bearing on the runners on the ground-surface. Across the upper portion of the front of the runners a draft beam or bar 6 is secured and has a draft-coupling 7 attached thereto. The draft-coupling comprises eyebolts 8, passed through the beam or bar 6 near the opposite ends of the latter, and to the said bolts link-rods 9 are movably attached and also loosely connected to front link-rods 10 by means of intermediate links 11, the link-rods being converged toward and attached to a draft-ring 12. The intermediate break provided by the links 11 permits the cultivator to be readily turned in opposite directions at the end of a field without jamming or bending the parts of the coupling device and with advantage in the appli cation of the draft force to the cultivator in the turning operations. Furthermore, in straight movement of a cultivator the draft device having the parts arranged as set forth compensates for a slight lateral shift or sliding movement to conform to irregularities of the ground-surface.

On the rear part of the upper edges of the runners bearing-blocks 13 are secured, and therein is mounted a shaft 14, having a central rounded section covered by a bearingsleeve 15, which is terminally held in the blocks 13. The opposite extremities 16 are squared and project outwardly beyond the runners. To one of the squared extremities 16 an adjusting-lever 17 is attached and movable adjacent to a tooth-segment 18, rising from one of the runners and projecting rearwardly adjacent to the seat 4, the lever 17 having a spring-actuated locking element 19 to engage the teeth of the segment and hold the shaft adjusted. The intermediate round section of the shaft 14 moves in its bearings for the purposes of adjustment, as just explained. On the opposite squared extremities 16 disk-box arms 20 are adjustably mounted and have forward upwardlyprojecting clip members 21 standing over the front ends of the said arms. The free extremity of the clip member of each arm and the adjacent extremity of each arm below the same have bolt-openings 22 formed therein in diagonal relation to receive adjusting-bolts 23, which respectively engage the front and rear edges of the squared extremities 16 of the shaft 14. These arms 20 are adjustable on the shaft extremities inwardly and outwardly 011 the squared extremities of the shaft for a purpose which will be more fully hereinafter set forth. Each disk-box comprises a tubular head or sleeve 24, from which a shank or stem 25 centrally pro ects, the box being thus given a T form. The shank 25 projects over and is held in close contact with the rear extremity of the arm 20 and is connected to the latter for adjustment by a pivot-bolt 26, located adjacent to the rear end of said arm and near the head 24;. The front extremity of the shank 25 has a transversely-extending slot 27 formed therein and necessarily arcuate, and engagmg said slot and the adjacent part of the arm 20 is a clamping-bolt 28. Through the medium of the adjustment of the shank 25 on the arm 20 the cultivating device held. by the head 24 may be positioned nearly in a straight line with respect to the runners or shifted to an angle of about forty-five degrees. The heads 24 of the boxes, as clearly shown by Fig. 5, have wear sleeves or tubes 29, which are longer than the heads and extend into central recesses 30 of sand-boxes 3 1, having inwardly-extending flanges 32, projecting over the opposite ends of the heads, the latter having free movement in the boxes on the sleeves or tubes 29. The boxes 31 prevent the entrance of sand, dirt, or grit to and render the securing belts or rods 33 more durable, the said belts or rods being passed through the sleeves or tubes 29 and the centers of the boxes 31 and serving to hold pairs of disks 34 in connected relation to the heads. The sleeves or tubes 29 prevent wear of the heads 24 directly on the bolts or rods 33, and when the said sleeves or tubes become worn they may be readily replaced. The disks are held in tight relation against the boxes 31 and unitedly rotate or revolve, during the operation of the cultivator, such movement being permitted by the loose engagement of the heads on the sleeves or tubes 29. It will be seen that the belts or rods are protected from wear by the accumulation of dirt or grit through the arrangement of the opposite ends of the sleeves or tubes within the boxes, as heretofore set forth. The outer disk of each pair of disks is smaller than the inner disk or blade, so as to permit the larger disks to operate in the bottom of the furrows and the smaller disks to cultivate the side of the furrow, and thereby more effectively level off the ground-surface. The

sleeve 15 of the intermediate portion of the shaft 14;, like the sleeves or tubes 29, also prevents wear of the intermediate p art of the shaft and may be replaced when found nec essary.

The cultivator blades or disks may be bodily adjusted inwardly and outwardly with respect to the runners or elevated and depressed though the operation of the lever 17, and in addition a further adjustment of the disks or blades may be accomplished to vary the angle thereof by shifting the shanks or stems 25 on the rear extremities of the arms 20. It will also be understood that the blades or disks may be thrown up high enough to entirely clear the ground-surface when it is desired to transport the cultivator to and from a field or other tract to be worked.

The improved cultivator will be found exceptionally convenient and effective in its operation, and it will be understood that changes in the proportions, dimensions, and minor details may be resorted to without departing from the spirit of the invention.

Having thus fully described the invention, what is claimed as new is 1. A cultivator having runners, a shaft mounted transversely of the runners, and sets of disk cultivating devices supported by the said shaft, said runners extending rearwardly betweenv the sets of cultivating devices and being provided with beveled clear ance ends.

2. In a cultivator, the combination of a frame having runners, a transversely-arranged shaft journaled therein and having laterally-projecting angular ends, sets of cultivating-disks arranged in pairs of different diameters, each pair of disks being connected by a central shaft, said runners extending rearwardly between the sets of disks and being provided with beveled clearance ends, boxarms connecting the shafts of the disks with the angular ends of the transverse shaft, each arm comprising two sections, one of said sections being provided with a clip attached to and longitudinally adjustable on the cooperating angular end of the transverse shaft, and the other section having a sleeve supporting the shaft of the coaeting pair of disks and a shank pivotally connected with the first-named section, and means connecting said shank and first-named section to permit the shank and set of disks supported thereby to be adjusted on an arc obliquely to the adjacent runner and toward and from the beveled clearance ends of the runners.

In testimony whereof I affix my signature in. presence of two witnesses.
